Best Lithium Battery for RV Reviews

This section will contain those product reviews I cited earlier. Each one will be a crucial piece of what ends up being your final decision. In fact, this info should enlighten you about what a top-tier RV lithium battery looks like and offers a customer.

1. Battle Born LiFePO4 Deep Cycle Battery

Our first option is known for its lightweight design. You see, the Battle Born LifePO4 Deep Cycle Battery only weighs 31 pounds, which is much lighter than most other models. How does this benefit a user?

Well, the lightweight design makes the entire install process much easier and doesn’t provide any unnecessary weight onto your rig. It’s also capable of being mounted in any position due to the lack of acid inside the battery. This aspect is another one capable of making the entire setup process straightforward.

But don’t think this product only offers convenience. As with all Battle Born lithium batteries, it has a rep for providing a great deal of durability. In fact, it features a 10-year lifespan that has proven more than capable of dealing with the wear and tear that comes with RV living.

I was pleased with the product’s built-in protections, as well. You’ll benefit from it having safety measures in place for any problems with either voltage or temperature issues. These protections will help increase the product’s durability by a great margin.

The product even has protection against short-circuits. Its inclusion shows Battle Born made sure to account for everything when making this outstanding lithium battery. The battery’s overall design was another standout aspect for me.

It’s made from 100% safe, nontoxic energy to ensure the product’s capable of lasting more cycles than almost any other battery. This design also ensures the product can charge faster than other models, which was backed up in its client reviews.

You couldn’t read two consecutive reviews without at least a mention of its unusual charging speed. As you can imagine, this feature has made it a popular choice in the rig owner community due to its increased convenience levels.However, this product does have one significant issue worth mentioning: its price is far more than I would be willing to pay for a lithium battery. It’s actually one of the more costly choices on this entire list. But these impressive features do make me wonder about whether I need to extend my budget a bit.

2. ExpertPower RV 12V 100Ah Lithium Deep Cycle Battery

ExpertPower’s 12V 100Ah Lithium LiFePO4 Deep Cycle Battery represents a perfect option for a rig owner looking to do a little off-the-grid camping. It fits into this situation due to its long-lasting ability, which dwarfs what a lead-acid battery could offer.

For instance, this battery will last anywhere between 2,500 and 7,000 cycles, depending on intended usage. It even comes with an expected 10-year lifespan where a regular lead-acid option offers 250 to 500 cycles and a 3-year lifespan.

This difference is quite expansive and shows why getting a lithium battery could be a much wiser choice. You should also love this product’s ability to hold above 12 volts for up to 90% of its capacity. It makes it much more efficient than you’d expect with a lead-acid type.

It’s just another way this 12-volt lithium RV battery proves to be superior for off-the-grid living any other type worth considering. The product’s lightweight design certainly doesn’t hurt its case, either.

You see this battery only 22 pounds, which makes it lighter than all lead-acid batteries and most other lithium batteries. You’re going to have a hard time finding another option more suited for marine, RV, or off-grid applications than this one.

But none of these features is the most impressive thing about it. This title goes to its built-in battery management system, which offers numerous protections. These protections include overloading, short circuit, overcharge, and deep discharge.

As a result, you won’t need to worry about any potentially dangerous situations occurring when it’s running. This type of protection is worth almost any amount of money. Ironically, price is another area where this product excels with it being affordable for a lithium battery.

I did have one complaint about this option, though, which concerned its customer service. They didn’t offer the kind of service I was expecting when I called them with a few questions. Multiple people in this lithium-ion RV battery’s reviews reported having similar issues. It’s not a good look for a company like ExpertPower.

3. Renogy 12V 100Ah Smart Lithium Iron Phosphate Battery

If you’re looking for an option with added versatility, this Renogy battery would be a great choice. This model has proven to be a sufficient battery for RV owners, marine appliances, and off-grid users.

Renogy made this product capable of working well in these situations due to its top notch battery cells. These cells ensure the battery will be able to last more than 4,000 cycles and provide a 100A continuous discharge current.

Both these features will help keep whoever buys this Renogy lithium battery very happy. Its ability to work in a variety of climates helps, as well. You can even expect this option to run in temperatures as low as -20 Celsius.

I don’t envision anyone reading this article will encounter these low temperatures, but it’s still nice to know you’d be covered. You should also know that this model features an extensive battery management system like the prior option.

This battery management system offers protections for temperatures, overcharging, overcurrent, over discharge, and short-circuits. It’s worth noting that this feature has received countless praise in the customer reviews for working correctly.

Due to this, nobody using this system should feel any sense of worry about a dangerous situation occurring. This system will ensure the product’s discharging and charging processes go off without a hitch.

You can also rest easy about the product’s install process. This area was another one that received widespread attention among other buyers. After all, it’s never a good idea to buy a device like an RV battery, which has a complicated setup. You’ll just be adding a great deal of unneeded stress into your life.But some customers did report issues about the product’s shipping and packaging. It seems the product has a habit of arriving inside beat up packing or later than expected. This issue wasn’t something I encountered when getting mine; however, it was noted enough by other buyers to warrant a mention in this review.

4. AIMS Power LFP12V200A Black 12V Lithium Battery

Campers with a solar power set up should look into buying AIMS Power LFP12V200A Black 12V Lithium Battery. It’s a sturdy, maintenance-free lithium RV battery with a level of durability, which rivals almost any other option.

In fact, you should have no problems getting ten years or up to 4,000 cycles with this device. This durability makes sure it ends up being a long-term investment rather than a short one. Other customers were more than happy with this aspect in their reviews, as well.

You also have to love the product’s outstanding thermal and chemical stability. These two aspects make sure its usage remains completely safe. It even ensures every battery cell is fused to add further additional protection and safety.

It doesn’t hurt that this battery has a lightweight and compact design, as well. But don’t worry, this lightweight design doesn’t hurt its effectiveness. This battery is still able to offer fast charging results and an incredible 350a peak for 10 seconds.

The install process shouldn’t be much of a hassle, either. Its been known to easily replace 12v, lead-acid, gel, or AGM batteries inside RVs, boats, commercial vehicles, and much more. This versatility makes it one of the more adaptable models on today’s market.

Buyers also get a choice regarding amperage as this option comes in a 100a and 200a variations. This choice provides a bit more control over the product’s effectiveness for each potential customer. It’s just another way AIMS Power ensures its product is as user-friendly as possible.

The product’s carry-on strap was an impressive trait, as well. This aspect will ensure carrying the battery around won’t be much of an issue. You’ll need this feature because the battery weighs a ghastly 77 pounds, which can be a little rough to carry.But sadly, this product isn’t a perfect option. It features an ungodly price tag that’ll empty your bank account without much resistance. Honestly, it’s easily the most costly option on our entire list. If you aren’t concerned about cost, this model should make your list. It’s an easy contender for the best RV battery.

5. Mighty Max Battery 12V 100AH Lithium Replacement Battery

Buyers looking for a simple, affordable option would be wise to consider Mighty Max’s Battery 12V 100AH Lithium Replacement Battery. It’s a low-price marvel capable of rivaling the performance offered by much more costly options.

This performance comes from its many impressive features. One of them is the product’s lifespan of 2,500 cycles, which dwarfs what a camper could expect from a lead-acid type. You should expect to offer top-tier results for a long time with this expected durability.

I was also impressed by its overall design, which consists of only top materials. This design should have no issues dealing with any travel problems, such as bumps or rough terrain. It’s even known to function well in both hot and cold climates.

As for its practicality, this design isn’t too heavy or bulky. The battery only weighs a light 20 pounds and should make the install process a much easier task. I didn’t even have problems moving this product around, which is a miracle given my lack of strength.

The install process itself is another appealing aspect offered by this device. Replacing a Mighty Max lead-acid or Gel batteries with this product should be a breeze. It was actually made to be a direct drop replacement for these setups.

I have to mention the product’s impressive BMS or battery management system, as well. This system protects the battery from over-temperature, overcharges, and short-circuits. You can rest easy knowing this product won’t fail or cause a damage situation when it’s running.

But the main standout feature would have to be its price. You won’t often find lithium RV batteries capable of providing these types of results available at this low price. Bargain buyers shouldn’t hesitate to buy this option immediately considering the excellent features and cost.However, I do have to warn you about one tiny flaw with this option. It doesn’t come with a wire harness or mounting accessories needed for the install process. This issue could be a huge hassle for people who aren’t directly replacing another Mighty Max battery.

6. Battle Born Batteries BB10012 Lithium Deep Cycle Battery Bundle

Battle Born Batteries continues to show its a fantastic manufacturer of RV lithium-ion batteries with this option. It features a long list of aspects that’ll make a rig owner’s life much easier on the road. One of them has to be its unique built-in Bluetooth communication.

This aspect makes setting up the battery a piece of cake. In fact, I didn’t even need the help of another person to get the job done. It’s an outcome that doesn’t often happen due to my typical issues doing these types of tasks.

You should take comfort in this product being made a US-based company, as well. This quality means it had to go under strict safety tests and regulations during its production process. Some foreign countries don’t have the same standard when it comes to manufacturing as the US.As for flaws, some buyers had issues with the included monitor being rather unhelpful. I didn’t encounter this problem during my experience as it worked perfectly. But it was cited more than a few times in the buyer reviews.

7. SHUNBIN 12V Lithium-ion Battery

SHUNBIN’s 12V Lithium-ion Battery offers a bit more choice than our other models. It comes in four variations: 100ah, 200ah, 300ah, 400ah. This amount of choice gives each buyer a chance to pick a battery based on their specific needs.

Each of these features will make sure your life becomes much easier on the road. Honestly, this product is a full-equipped lithium battery, which shouldn’t have any problems delivering top performance. What more could a rig owner want from one of these devices?Well, I wasn’t too thrilled with their customer service or product shipping. The battery arrived inside beat-up packing, and I went to call them about it. But I couldn’t get a hold of them and had been put on hold for a long time.

Their answers weren’t constructive when I did get through, either. These issues aren’t what you come to expect from a brand with a great rep like SHUNBIN. However, it could have been an isolated incident as I didn’t find another customer who endured these problems.

In fact, a vast number of customers were willing to hurl praise onto its design within their reviews. I have no doubt this model will handle any situation that comes up during your travels.But I was a little disappointed to learn a company outside the United States made it. This issue is more of a preferred thing, but it’s still worth noting as someone reading our article might not be comfortable buying products made in foreign countries.

However, I do have to state most customers had only positive things to say about this device. It was a challenge to find a person who was even willing to mention something negative.

Best Lithium Battery for RV Buyer’s Guide

Rig owners should know at least the basics of RV lithium batteries. One of the first things to know is you shouldn’t get them confused with actual lithium batteries, which happen to be non-rechargeable. Motorhomes instead use lithium-ion batteries that are designed to supply, store, and then recharge power.

Nowadays, most RV owners are looking for the fastest, most durable, and toughest battery types for their rigs. This approach leads to them choosing a lithium-ion battery for their own RVs.

But how does one pick the perfect option? Well, this section will discuss all those crucial buying factors with a lot of detail. These talks should make choosing the right one for your rig an easy task. It’s just a simple matter of following what we discuss in this buying guide.


One of the primary factors will be your RV battery’s weight. Before choosing any battery type, it’s crucial to determine whether it’s the right weight for your rig. After all, it’ll need to be stored inside your rig. You’ll need to ensure you have enough engine power and space to carry it on your trips.

In any case, more will always be a better choice when storing energy. This statement is especially true for rig owners looking to do off-the-grid activities, such as camping or boondocking. You should think about how many batteries will be needed to do these activities and their combined weight.

I should also mention that the battery’s weight will be dependent on its overall design. As a result, every buyer should look over the battery’s dimensions. Please consider how they would affect how they get stored on your rig.

Overall, rig owners will usually pick lightweight and compact batteries. You can imagine how much easier these designs make the storing and install process. The dense quality will help these batteries deal with the wear and tear or road life.

Ease of Use

The using process tends to be an overlooked factor when buying RV lithium batteries. In fact, it’s essential to consider how natural the product is to use during this process. One of the aspects to look for is the battery’s flexibility in its charging process.

It would be beneficial to get an RV lithium battery that can work with multiple power sources for the charging process. These products will be able to charge from a campground’s power supply, generators, or even some can charge using solar or wind power.

You can imagine how a battery with this versatile charging powers would help out a person on the road. A buyer should look into each battery’s operating abilities, as well. For instance, will the battery work well when the engine is running or only when parked?

I suggest thinking about this factor and how it fits into your situation. Anyone who wants to use their battery frequently should invest in one capable of running well when you’re driving it. It’ll make your RV trips a much less stressful event.

Lastly, I would make a point to look into how easy it is to understand the battery’s readings. You shouldn’t have a difficult time figuring your battery’s power levels. If you do have trouble, it could negatively impact your trip. Read through other people’s buyer reviews to give a better handle on this potential issue.


Rig owners tend to misunderstand one thing about their RV’s strength: their rig’s only as good as the battery, which happens to be powering it. After all, an RV with a bad battery isn’t going to be much use on your trip.

You should take this into account when picking out an RV lithium battery. In other words, make sure only to choose an option with a solid rep for being durable. It’s essential to realize the materials used in its creation will have a massive impact on this factor.

As a result, buyers should only look to buy batteries made from top materials. This action will ensure the product works better, especially when it comes to energy and power. Another thing to look out for is the product’s ability to deal with life on the road.

The travel durability of these batteries will be determined by how many vibrations or bumps it can survive. A top-tier option should be able to handle all the factors that come along with traveling on various terrains. It shouldn’t matter whether you’re on some bumpy backroad or the highway.

You should find this info in each model’s product description. Most brands will provide a general guideline for the battery’s lifespan. Due to this, you can make an educated guess about how long the battery will be able to help out your rig.

Another area to consider would be product’s design. Some top models will come with extra features that can help improve its overall durability. For example, a lithium battery might come with sealed housing, handling features, or extra sturdy housing design.


You’ll also need to determine the correct power aspects for your chosen RV battery. This task will consist of examining three pivotal things. The first aspect will be your battery’s charging speed, which will have a massive impact on your travels.

After all, the charging speed will impact your entire trip timeline because its stored energy determines how far you get. Buyers will need to consider the charging time that they’re willing to deal with during a trip.

The second aspect worth considering is your chosen battery’s capacity. You’ll need to figure out how much each battery can store because it’ll determine what tasks it can support effectively. In other words, find out how much each model can disperse in a specific period and match it to your expected energy usage.
